Efficiency of Enhanced Distance Active Contour (EDAC) for microcalcifications segmentation

Abstract

In this paper the boundaries of microcalcifications in mammogram are segmented images by using the Distance Active Contour (DAC) method. However, the DAC requires longer computational time to finish the segmentation process. Thus, the Enhanced Distance Active Contour (EDAC) is proposed to overcome the problems. The efficiency is measured in terms of time lapse and number of iterations. Results obtained show that the EDAC has successfully reduced the processing time as well as the number of iterations. In addition to that, the boundaries of microcalcifications have been successfully segmented by the EDAC. It is also found that the efficiency of EDAC is better than the DAC. © 2011 Springer-Verlag.
